CAN-CLOSING MACHINE.

Application filed August 18, 1915.

b all whom it may concern:

Be it known that I, Ivan F. VVAnMn, a citizen of the United. States, residing at Syracuse, in the county of Onondaga, State of New York, have invented certain new and nseiul Improvements in Can-Closing Machines, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference a i za rkcd thereon.

The invention relates to new and useful improvements in can closing machines, and more particularly to a machine for closing a [illed can.

An object of the invention is to provide a can closing machine of the above character with a seaming head for connecting the end to the body of the can, which seaming head is positively rotated, and wherein the actuating parts of the seaming headthat is, the cams for the seaming rolls and the stripper rod for stripping the can from the seaming head are also positively moved up and down by cams which are operated from the same shaft which rotates the seaming head, but at a slower speed than the shaft.

A further object of the invention is to provide a closing machine of the above character, with means for supporting the filled can. and for raising the same into engagement with the seaming head, which supportin means is raised and lowered by a cam on the shaft which actuates the parts of the seaming head.

A still further object of the invention is to provide means for placing a can end on a support underneath the seaming head, which support is also provided with a tapered rounding up and centering ring for the can body, which can end placing means is constructed so as to move concentrically about the axis of the seaming machine conveying a can end from the stack to the support underneath the seaming head.

A further object of the invention is to provide devices cooperating with the can end feeding means, which devices include a. member for engaging a can as it is fed to the seaming machine and travels with the can while in engagement therewith.

A still further object of the invention is to provide a can end feed controlling means, wherein a member is brought into engage- Specification of Letters Patent.

ment with. the upper end of the can and caused to travel therewith, which member is moved downwardly into engagement with the can by yielding means.

A still further object of the invention is to provide means for removing the closed cans from the support underneath the seam ing head, which includes a rotating member having spaced arms for engaging the can and wherein said rotating member is posi' tively but intermittently actuated by gears.

These and other objects will in part be obvious and will in part be hereinafter more fully disclosed.

improved closing machine consists general y ()l' a vcrtieal standard or Frannwork 1 for supporting all the operating parts of the machine. lilounted to rotate about a vertical axis on this Frame work is a seaming head 'lhc seaming head 2 is rotated by a main operating shaft 3. This lllillll operating shaft is geared to a vertical shall -i which actualcs the operating parts ol the seaming head that is. the rains l r controlling the seaming rolls and the stripper pad tor stripping the closed cans from the seaming head. The can to he rloscd is plarcd n a support 3 and is raised by an upward movement of the support into opera tivc engagement with the waning head. Just directly beneath the scanning head is a supporting plate 6 for the can ends, so that as the can body is raised the end will be seated therein. The can bodies are placed on this support 5 by a rotating drum conveyer 7 and the are stripped from the sup port after the can is closed by a rotating stripper 8. The drum and the rotating stripper are both actuated llUlJ] a horizontal shaft which in turn aotuated from an auxiliary vertical shaft geared to the main vertical shaft 4.

The can ends are placed in a stark holder ii and are fed on to the support (I by a recip rocating pusher 8, which in turn is actuated from the auxiliary vertical shaft above referred to. This pusher is capable of being disconnected from its reciprocating means and the connection is (anitrolled by a no-ean no end controlling mechanism 10, which is positively actuated from the main shaft of the machine and is adapted to engage a can as it is fed underneath the seaming head and travel therewith while in engagement with the can.

Scaming head.

Referring more in detail to the drawings, the seaming head 2 consists of a supporting head 11, on which is pivoted a lever 12 earn/- ing a seaming roll 13. A second lever 14; is also pivoted on this head and carries a seaming roll 15. The supporting head 11 is fixed to a sleeve 16 which is mounted to retate in a suitable bearing 17 carried by the main frame. This hearing is provided With a suitable roller end thrust bearing and also a suitable roller lateral tl'irust bearing.

Fixed to the upper end of the sleeve 16 is a hovel gear 1? which incshes with the bevel gear lH on the end ill the main shall I). This inain shalit is mounted in suitahlc hearings in the supporting lraine and on the outer end ol' the shalt is a cone I'rirtion pnl le v Ill. This l'rirtion puller may he slid end wi e on the shaft by a yoke 2U whirh is piv rted at Al to the 'l'rainc and carries snilahle rollers 22. running in a groove in the huh ol' the l'riction pulley. A hand lever J45 is piv lrd at Lil to the i'ranic ol the machine and this hand lever is pivoted at 2-) to a link L which link at its other end is connected at '27 to the yoke :20. The portion of the hand lever extending beyond the pivot 24 is adapt cd to h nuovcd into alincnlent with the link Eli. The pivotal ronnection helweon lhc lever and the link inows slightly hy the ll'il'l rcir lrl; so thnl these parls will la hold in thi positi n A st p L ii peralinp ilh the h \i-r 2 selwcs as an alullincnl l'or holding th parts as slated.

Also mounted n lhr lali II and turnip); l'rcithereon is a hell wheel 35' whirh has a ronc i'riction surl'arc Ill) adapted to ill on gagcd hy the l'rirtion surl'aion the pulley l9. 'hcn the pulley 19, which may slide end wise on the shaft, is moved to the left as viewed in Fig. 3, these parts are brought into engagement and the main shalt will he oper ated from the belt wheel. \Vhen. howeven the pulley 19 is moved to the right, as viewed in this figure then it is lno-nght into engage ment with a tapered flange Ill, which open ates as a brake to stop the machine. A spring 35 2 normally operates to force the cone pulley 19 into engagement with the belt wheel. When the lever 23 is thrown into the position shown in Fig. 2 the cone pulley i; moved out of engagement with lhc hell pul hay compressing the spring $12, and, into on gagenient with the braking flange .31. It will. thus be seen that through this control ling mechanism the spring will hold the parts in driving connection.

Extending through the sleeve .10 is a second sleeve 33. his sleeve 33 carries the cam 34; which operates the seaming levers 12 and 1st. The construction of this operating cam and the manner of actuating the seaming levers thereby, so that the first lperation roll performs its function. before the second. operation roll is brought into contact with the can end is well known in the art and further description thereof is not thought necessary. The sleeve 33 carrying the operating cam is moved up and down by a lever 35 which is pivoted at 36. Said lever is so connected to the sleeve that said sleeve may rotate freely and this sleeve 33 is connected to the outer sleeve 16, so as to rotate with the seaming head and thus preserve the relation etween the operating rains for the scan]- ing levers and said levers. The lever is raised and lowered by a reciproeating cross-head 37, which is guided by a bearing in the frame and has a roller 38 which runs in a cam groove 39 formed in the cam drum 40. This cam drum 40 is keyed to a sleeve 4.1 which surrounds the vertical shaft 4. The vertical shaft 4 car ries a bevel gear 4-2 at its upper end which meshes with a bevel gear 4L3 keyed on the main shaft 3. At the lower end of the shaft 4-, there is a gear 4-4 which meshes with a gear on a counter-shaft 46. This counter-shaft 46 carries a gear 47 which meshes with a near l8 fixed to the sleeve 41. "he purpose of this train of gears between the shaft land the sleeve i'l is to reduce the rotation, so that the sleeve 41 will rotate very much slower than the main sha ft 3. ll is desired that the seaming head shall rotate at a very much greater speed than the controlling shaft for the cams which operate the seaming roll as the seaming head makes several rotations before the seaming levers have been shifted to complete the operation of seaming". This cam groove 3%) \vh'n-h op crates the sleeve 33 through the lever 35 is constructed so as to move the sleeve positively. The cross-head 37 reciproeates in a line substantially parallel with the axis of the sleeve, so that the movements imparted by the cam are positively and directly transmitted to the sleeve.

Extending through the sleeve 33 is a rod 46. This rod carries a stripper pad 47 at its lower end which is located in a recess formed in a chuck it. The chuck 3% is mounted on the supporting head for the teaming rolls, so that the seaming; head ninja rotate freely above the chuck and the chuck is held from rotating by being splined to this rod 46. The chuck is held from endwise movement by being attached to a sleeve 49 which has a flange at its upper end for supporting the chuck. A roller thrust hearing is located between the supporting head and the chuck. The rod 46 is raised and lowered by a lever 50 which is pivoted at 51. to a suitable bracket carried by the main frame. Said lever is raised and lowered by a cross-head 52 which carries a roller 53 cooperating with a cam groove 54 in the cam drum 40.

From the above description, it will be apparent that I have provided a seaming head wherein the seaming rolls rotate in a fixed plane-that is. have no up and down movement except, of course, that each seaming roll swings in the arc of a circle when moving toward and from the cans. Said seaming rolls are positively driven from a direct. gear connection with the main shaft. The cams for controlling the levers which carry the seaming; rolls and also the ejecting pad are positively raised and lowered by cams carried by a vertically rotating shaft which is driven from the main shaft at a different speed than the main shaft. The operaling parts. therefore. for the controlling cams referred to and the ejecting pad are com paiativrl f u in nuwber. Hl'rplp in eon struetion and ellieient in action owing to the positive movements thereof and the substan tially direct lines of thrust.

00m body support.

The filled cans to he closed are llltlCP-fi one at a time on the support 5, which. as shown in the drawings. consists of a supporting; head or disk mounted on a stem 55 which may be moved up and down in a suitable bearing 56. This stem at its lower end haa threaded connection with a collar 57 and the collar 57 is connected to a lever 58 pi otcd at 59 to the frame of the machine, and this lever is moved up and down by a roller 60 running in a cam groove (31 in a rain drum 62. which is keyed to the sleeve 41. This cam drum 7:2 travels in unison with tln t? whi h mov s th sean u i rolls into contact with the can and also con-- trols the ejecting pad and the cams are so constructed and timed that the can body is raised by the lifting of the support Ii. o 1:: to engage the seaming head when the rolls are separated. after which the cam groove 39 operates first one seaming roll and then the other and when the end is finally double seamed to the can body, then the support 5 is lowered into position for stripping the closed can therefrom.

The stem which carries the can body support 5 is threaded into the collar 57. a above noted. and this permits the support be adjusted relative to its operatii'ne' lever 59 for raising and lmvering the same. Mount ed on the upper face of the FHPPUI: i is a hardened plate 6? and also attarhcd to this support is a guide (it. The bearing! 56 for the support is carried by a supporting plate which is adjustablv mounted on the frame of the machine. This sup 'iorting plate is bolted to the frame by suitable bolts which pass tln'oug'h slots 6b in the ertical plate carrying the hearing. A thread ed shaft 67 engages the support and this shaft has spaced flanges 68 which engage a rib 69 in the frame. This engagement of the flanges with the ribs permits the shaft to be rotated but holds the same from endwise movement relative to the frame. By loosen-- ing the bolts 65 and turning the shaft 6? the supporting plate may be raised or lowcred. This raising or lowerii'ig of the sup porting plate does not, of course, change the reciprocating position of the support 5 for the can body. This can onlv be changed by shiftin the (ollar 57 on the lower threaded end of the stem carrying the support i The purpose of this adjustment of the sup-- porting hearing will be more apparent in r'imi |'i)t|ll(t"llltll with the dcsrrimion of the rouvevrr Wllll'll plurus the tilled ran on the support 5.

This conveyor drum 74 is mounted on a shaft 75 which is journaled in the bracket T1 and in the hearing 56. Said hearing it is formed with a bushing 76 for said shaft. see Fig. The drum Tl is provided with a spiral thread TT and as the drum rotates this spiral thread will move the filled (ans toward the (losing tlltlt'lllllt. ()no side (it tho ran rests on the drum. while the other side rests on a supporting plate 78. This supporting plate and the drum extend to the can hotly support 5 and one side of said support is cut away. as shown in Fig. 4. (so as to permit the filled cans to he moved by the drum on to the support 5 without spilling the contents thereof.

In Fig. 5 of the drawings. I have shown the support 5 in its raised position in full lines and in dotted lines the lowe position of the same. The guide rails 72 and 73 are adjustably supported, so that they may be shifted for varying sizes of cans. The shaft 75 carries a bevel gear 79 which meshes with a bevel gear 80 connected to a short crossshaft', shown in dotted lines in Fig. 4. nd this cross shaft carries a worm gear 81. which meshes with a gear 82 on the huh of the disk 70. so that as the drum is rotated this disk 70 will be rotated and place the cans one after another on the drum and the rotation of the drum will convey the cans to the support 5. The shaft 75 at its other end is provided with a bevel gear 83 which in turn meshes with a bevel gear 84 attached to a sleeve 85, see Fig. 6. The sleeve 85 is formed with a projecting flange 86. This sleeve is mounted on a horizontal shaft 87, which in turn is mounted to rotate in a suitable bearing in the bracket carrying the shaft 75. Attached to the outer end of this shaft 87 is a disk 88 and this disk 88 is connected with the flange 86 by a breakable pin 89. This breakable pin 89 is adapted to be placed in an opening formed in hardened sleeves mounted respectively in the flange and in the disk. The purpose of this connecting pin is to permit the disk 88 to b disconnected from the flange 86 if the parts of the feeding mechanism should he clogged by a can body. Under such conditions, the connecting pin Wlll be severed by memes these hardened sleeves. The shaft 87 at its inner end carries a h-eiel gear Sit) which u'ieshcs with a bevel gear ltl spliued to the shaft 92. The gear 91 is capable of being slid up and down on the shaft 92 when the support for the shaft 87 is adjusted vertiuallv through tho artiou ot' the threaded shalt til. :lhovo desrrihtal. This vertical sha'l'tv U2 is mounted in suitahlr hearings in the frame of the uutchino and rarrios a gear l at its upper end which meshes with a gear tl-t which in turn is keyed to the sleeve 41, so that as the sleeve 41 rotates the gear 9t otates the gear 933, which in turn operates the shalt H2 and the shaft 92 rotates the shaft 87 and this rotates the shaft 75 operatimg the feeding drum. It will he noted that all these operating parts tor the drum may he adjusted vortirally hy rcleas in the bolts ()5 and turning" the threaded shaft (37. The purpose of this adjustment s to adapt the machine for operating upon runs of varying sizes.

Strip In;

Tho stripper 8 for removing the i-losed vans from the support 5 is in tho form of a l'ourhr u wheel. Each arm tit projects ra dially from the hub of the wheel and is adapted to engage a tilled can on the sup-- port. 5 and when this Wheel is rotated the tilled run will he moved from the suiinaort. into a suitable receiving chute. The stripper wheel 8 intermittently operated by the following mechanisn'i.

Said stripper wheel is secured to the upper end of a short shaft which is mounted in the same bracket which rarries the coin veye r. On this shaft is splined a gear 97 whirl] meshes with a gear 98 keyed. to the huh ol' the gear 83 which drives the shaft 75. The stripper wheel is located at a suliicient distance above the support 5 to permit its being raised and lowered for presenting the can to the closing machine, as clearly shown in Fig. 5.

(tan (and feed.

The can ends are placed in the stack holder 9, which is mounted in a suitablesppporting bracket 103. This bracket is attached to the frame of the machine. Said bracket carries the supporting plate 6, which extends underneath the seaming head and said supporting plate is provided with a tapered opening 104-, which centers the can body and rounds up the same when it is raised by the lifting of the support 5 through said opening. ()n the upper face of the plate is a seat 105 for the can end. The bracket; 103 between the stack holder and the seat 105 is formed with a guiding recess 106 for the can ends. The can ends are taken one at a time from the stack and moved along this guiding recess on to the supporting seat 105 by the pusher S. The pusher 8" consists ol a reciprocating plate 107 see Fig. 8. which has a tripper blade. 103 adapted to separate the lowermost can end from the slack and carries the sann along the guiding recess 100 to its seat un derneath the seaming head. This stack holder consists of a plurality ol' rods 10$) which are rai'ried by the stack holder ring 110. and the pusher plate 107 moves underneath the stack holder ring. Said pusher plate operated by an oscillating arm 11.1. Said arm carried by a supporting collar 112. which is mounted to oscillate freely on the sleeve 41. so that the axis of the arm is the centering line or axis of the seaming machine. This arm is provided with a radial groove 113. ()n the upper end of the shaft 92, I have fixed a disk 114 which car ries a pin 115 having a roller which runs in this groove 113 see Fig. 6. The guiding recess for the can end and the pusher plate 107 all rurve about the axis of the sleeve 41 or the pivotal axis of the arm 111. This arm 11] is also curved to conform to this path of travel of the pusher latch and the supporting bracket 103 likewise. curved. The curved portion of the arm 111 is indicated at 116 in Fig. 8. The pusher plate 107 has adjnstably attached thereto a latch plate 117. Said latch plate is connected to the pusher plate by suitable bolts 118 which pass through slots 119 and are threaded into said latch. A latch 120 is pivoted at 121 to the latch plate. This latch is normally spring pressed in a downward di rection by a spring 122. Said latch has a shoulder 123 which is adapted to be engaged by a plate 124 carried by the cur ed portion 113 of the arm 111. Said plate is pivoted at 125 between spaced lugs 123 at the outer end of the arm 110 and is held in tixed position relative to the arm by a breakable pin 127. Said pin is adapted to be inserted in suitable openings in hardened sleeves 128 carried by the lugs 120 and extends through an opening in the plate 124. Said plate is preferably of hardened metal. hen the parts are positioned. as shown in Fig, 8 the latch is in engagement With the plate 124, and the reciprocating move ments of the arm 111 will be impartial to the pusher plate 107, and for each oscillation of the arm 111 a can end will be taken from the stack and placed on the can end sup port underneath the seaming head. If. however. the latch 120 be raised, so as to be dis engaged from the plate 124, then the reciprocations of the arm 111 will not impart any movement to the pusher plate 107. \Vhen the parts are locked. as shown in Fig. 3, and a cover becomes jammed, then the hardened plate 124. cooperating with the hardened sleeves, will. shear the pin 127,

thus releasing the plate 124, which will turn about its pivotal point 125.

N0 can no end mechanism.

The means for controlling the feeding of the can ends is shown in detail in Figs. 11. 12 and 13. The main frame 01 the machine has outwardly projecting ribs 129 forming a guiding recess 130. in which reciprocates a supporting bar Formed of two sections 131 and 132. The section 131 carries a roller 133 which runs in a cam groove 13-1 in a cam disk 135 connected to the sleeve 41. The section 132 carries a pin 1.30 which projects into a recess in the section 131. and a spring 137 located in this recess normally holds the pin at the lower end thereof. The cam groove 134 operating upon the roller 133 reciprocates the sections 131 and 132. but this spring and pin connection between the sections permits said outer section to more outwardly relative to the inner SOC tion. llxtending laterally from the outer section is a bracket 138 carrying a hearing sleeve 139. Pivotally mounted in this bearing sleeve is a short shaft carrying an outwardly projecting arm 1-1-0. This arm 140 at its outer end is provided with parallel ribs 141 and a disk shaped member 142 which is adjustably connected to the arm, so that the same may be shifted in a direction parallel with the ribs by a securing bolt 143. Said bolt passes through a slot 144- in the arm 140. At the lower end of the shaft carrying the arm 140 is a second. arm 145, which carries a roller 146 adapted to engage a cam 147 mounted on the hub of the cam disk 135. This arm 140 is reciprocated up and down through the action 01 the earn 134 and is moved sidewise through the action of the cam 14-7. This arm is so positioned and the cams are so timed that the arm comes down over the top oi a filled can on the conveying drum and, if a can is being fed along by the drum, said arm will engage the can between the ribs 141 and the disk 142 preferably rests on the top of the can. The arm 140 is moved sidewise at a ropcr speed, so that this plate resting on t. e top of the can Will travel with the same along the eonveyer. In other words. the arm 140 has in effect four motions first. a downward movement until the plate engages the can body: then a lateral movement with the can body, thence an upward movement. and finally a backward movement to its normal position.

Mounted on the laterally projecting bracket formed integral with the rib 129 is a releasing pawl 148, and this releasing pawl is pivoted at 149 and has an upwardly projecting arm 150 and a laterally projecting arm 151. This laterally projecting arm 151 1311011115111} forced upwardlv by a spring 152 and this holds the outer end of the pawl 1-118 resting: against a. stop screw 153. Also mounted on this bracket is a. holding; pawl 151 which is pivoted at 156 and normally sprin pressed downwardly by a sprin g 157. Pro iecting laterally from the bracket 13% and reciprocating with the same is a pin 15%. This pin is adapted to engage the arm 15] when moved downwardly and to engage the lo king pawl lot when moved upwardly. The releasing pawl 14B is adapted to lie in the path of reciprocation of the latch 120. see Fig. 11.

\Vhon the sliding bars move downwardly through the action of the cam 131, if there is no can body on the conveyor, then the bracket arm 110 will move its full stroke. but, if there is a can on the conveyor. then said arm will engage the top of the. can and will more no further although the re eiproeatiue slidingsection 131 will continue its downward movement. This is permitted by the spring and pin connection 131' and lIlT. The upward movement of the arm ll and the bracket carrying the same causes the pin 158 to engage the locking pawl lol and release the tripping pawl so that the spring 152 will throw the same to the posi' tion shown in Fig. 15. A downward movement of the arm 140 and the bracket supporting the same carries the pin 158 down wardly. If this movement of the bracket is not limited by a filled can, then the pin 158 will strike the arm 151 and shift the upper end of the arm 150 of the releasing pawl. so that it will be engaged "by the holding pawl 151. \Vhen this releasing! pawl 1.49 is held by the locking pawl 151. the end of the pawl 14.? will be engaged by the latch 120 and this will cause the latch to swing" upwardly releasing the latch from the holding plate 1:2 1 and the pusher plate 107 will not be moved by the swinging of the arm which feeds the can ends. On the other hand, if the locking pawl 15-1 is released, then the spring 152 will throw the releasing pawl 148 to a position so that it. will fail to lift the latch to release the same. It will be noted from above that the loele ing pawl will be operated to hold the releasing pawl 118, whenever the arm 140 makes a full stroke, so that the releasing pawl is swung to a point to be engaged by the locking pawl and whenever a. can body limits the movement of this arm 140. then the locking pawl becomes ineffective for the reusonthat when thearm 150' is tnoved to the left by the spring the hook on the end of the locking pawl will not engage over the same. It will be apparent therefore, that I have provided mechanism controlled. by the can bodies fed along the conveyer drum for determining whether a can end is to be fed underneath the seaming head. If there is no can bodv. then there Wlll be no can end fed, and when a can body is fed under the seaming head a can end will be also fed on to the support beneath the seaming head ready to receive the an body when it is litted by the support 5,

Operation.

The operation o'l my device will be up parent from the detail description of the various parts given above. The tilled cans are placed on the feedii'ig-in disk 7 and are carried around and delivered one at a time to the conveyor 71 which feeds the same one at a time on to the support 5. A can end. is taken from the stack by the slidin pusher and is moved underneath the seaming head on to the seat on the supporting plate 6. The support 5 is raised through the action of the cam groove )1 and the tapered opening; in this supporting plate (3 rounds up the can body and ent rs the. same. so that the can end will be seated therein. 11 will be understood that the ejecting pad moves down wardly so as to engage the can end and aids in sealin g the same in the can body, after which the ejector moves up with the can body until the can is chucked. The seaming head is continuously rotating about the chuck and the controlling cross head 37 is then lowered causing the seaming lever carrying the first operation roll to swing and perform the first operation. after which this roll is released and the second opcation roll engages the can end and perforn'is the final operation. The closed can is then ejected tron) the seaming head by the ejecting pad which moves downwardly in time with the support 5. The stripper wheel is then given a quarter turn through the action of the in termittent gear driving connection therefor, and this forces the closed can from its support into a suitable receiving chute. Vli' hen there are no cans being carried along the conveyor, then the can end feed controlling: device will reciprocate its full length and the releasing pawl will be held in position for causing the latch to disengage the pusher slide, so that no can end will be fed underneath the seaming head. The conveyer and also the support for raising the cans to the seaming head may be readily adjusted for closing different sized cans. The can end feeding device may also be suitably adjusted to accommodate difl ercnt sized ends.

It is obvious that minor changes in the details of construction and arrangement of parts may be made without departing from the spirit of the invention as set forth in the appended claims.
